Losing Dez does more damage. It will be a huge *** dominio affect. You lose Dez you might as well trade Romo and rebuild.
If we lose Dez we either have to trade for a WR close to his talents or equal(which we won't because we don't even want to pay Dez) so therefore we would have to trade for 2 pretty decent WR's. Which would cost draft picks, because we would not want to trade any of our core guys. To be honest the only guys worth a damn on this team, are Romo, Dez and the O-line. Nobody else holds any real weight.
So that brings me back to trade Romo and rebuild. Why? Because if we lose Dez this year that means we would have to draft a guy, and its rare to hit on moss/odb types in their first year. Most 1st year WR's take about 2-3 years to develop. Romo only has about 2-3 years left.
So we can keep playing Chicken with Dez all we want, but the real harm is being done by the Cowboys.
Either way, Dez will get his money, regardless from us or someone else, whether we like it or not.
